I posted over on the other thread. I bought it and have run it through the mill for the last couple of hours. If you have plans of using Mixbus, this program is a MUST-HAVE! Check the other thread on this sale for details about installation and registration. I loaded up some projects in X3e, exported them as OMFs, Xchange runs automatically to open Mixbus. It prompts you to find your OMF, browse, click to open and BOOM! Every track is aligned and ready to go. I don't know what it is but Mixbus really does have a very smooth, analog character to it.
It is absolutely worth the money. If you have any trouble figuring out how to use it post a thread here or message me and I will be more than happy to help.
BTW, I was loading my projects in to X3e 64 bit and exporting the OMF which opens in Mixbus 2 which is 32 bit. All of this in Windows 8.1. It works without a hitch.
